[Xastir-dev] Broken station location

[Gerry Creager N5JXS]

TT-3 doesn't need the inversion.  OnCores prior to the M-12 are power 
hungry, but stellar little receivers.  SV6's are also power hungry.  the 
SK-8 from Trimble, Rockwell/Connexant Jupiter, most of the SiRF-based 
chipsets, and the Motorola M12 are better for low power consumption.

Also, while most... really, I guess all... of these need a preamp'd 
antenna, several provide and work with 3.3v antennas, and those have had 
power consumption cut as well.
